J. GARRIC DEVICE FOR THE MANUFACTURE OF STOCKINGS Filed April 6, '1945Patented May 20, 1947 DEVICE FOR THE MANUFACTURE OF STOCKINGS JeanGarric, Troyes, France, assignor to Societe Industrielle De Bonneterie,Troyes, France Application April 6, 1945, Serial No. 586,988 In FranceApril 7, 1944 2 Claims.

This invention relates to a device for carrying out the improvementsforming the subject matter of my previous Patent No. 2,313,294 datedMarch 9, 1943, relating to the manufacture of stockings on flat knittingmachines with sinker bar, of the Cotton system, the general termstockings also comprising the similar articles such as half-stockingsand socks.

The invention relates to the manufacture of stockings comprising theknitting of the leg and the heel in one operation on ordinary knittingmachines comprising a needle bar with a fixed central section inopposition to the so-called frames with cut or gapping needle bed orwith a door, or movable hinged central section whose needle bar isprovided with a central movable part which can be shifted so that theneedles with which it is provided can be brought out of action at theopportune moment in order to permit the knitting of the tongues of theheel.

The invention also relates to the execution, on said ordinary knittingmachines having a needle bar without movable central section, accordingto the method described in my above mentioned application, for each ofthe lateral sole entrance parts (that is to say of both parts of thebeginning of the sole which lie outside the instep or front part of thefoot), of the unravelable edge adapted for the later connection, outsideof the knitting machines or frames, of said lateral sole entrance partswith the tongues forming the heel; said method being characterized bythe fact that the first course of loops 'of the sole, when finished, isrendered unravelable on said lateral parts through the transferring ofone loop out of two on every other needle, consequently from its needleonto that following its neighbour, each needle carrying a 100p and everyloop out of two being transferred from its needle to every other needlewhile the other loop is not transferred.

The device which forms the subject matter of the invention and which isprincipally remarkable by the simplicity with which it permits to effectthe adaptation of old knitting machines to said new technics, ischaracterized, as a rule, by putting into action, for obtaining theunravelable course, on the lateral sole entrance parts, of the picotedge bar in combination with a knife having a width corresponding tothat of the instep or front of the foot and coming to insert itself atthis moment between the transferring hooks of the picot edge bar and theneedles corresponding to the front of the foot, thus preventing theloops to be taken by the transferring hooks coming to lie opposite theneedles of the front of the foot.

A form of execution as well as a modification will be described now andare shown diagrammatically and by way of non-limitative example inFigures 1 and 2 of the appended drawing, which are front elevationalviews of said form of execution and of said modification respectively.

In Figure 1, l is the needle bed of a flat knitting machine with sinkerbar of the Cotton system, said bed having a fixed central section, and 2are the needles; 3 is the picot edge bar which is provided withtransferring hooks 4, there being one transferring hook for every twoneedles.

The picot edge bar 3 is used without any modification and, for thispurpose, one uses in combination with said bar a knife 5 formed, in aknown manner, of a brass or steel blade or a blade of any other materialpivotably or slidably mounted in order to be able to insert itselfbetween the transferring hooks 4 and the needles 2. Said knife is putinto action at the moment of the execution of the unravelable row of thelateral sole entrance parts and its width is chosen so that it can actupon the needles comprised in the interval I corresponding to the instepor front part of the foot and thus prevent theloops to be taken in thisinterval (I 1 designating the width of the unravelable row of the lefthand lateral sole entrance part and l the width of the unravelable rowof the right hand part). The picot edge bar 3 is controlled so that thetransfer which it effects in the parts I and I has an amplitude of twoneedles towards the right or the left.

Of course, improvements can be brought to the details without departingfrom the scope and spirit of the invention.

For instance, in a modification, the picot edge bar instead of beingmade integral on its whole length can be made of two equal parts 3 and3' each of them being mounted on a different axis so that both saidhalves when suitably placed for the unravelable row can transfer, theone on the left and the other on the right, either from insideto'outwards, or, and preferably, from outside to inside, as indicated bythe arrows, the knife 5 working in the same manner as described above inorder to avoid the transfer on the instep, both lateral left hand andright hand sole entrance parts being thus perfectly symmetrical.

I claim:

1. A device for the production of the unravelable edge of the lateralsole entrance parts of the sole of stockings on flat knitting machinesof the type having a sinker bar and a needle bar without a movablecentral section, said device comprising a. picot edge bar put intoaction and controlled so as to effect a transfer of an amplitude of twoneedles in combination with a knife having a width corresponding to thatof the instep or front part of the foot and located above the instepneedles.

2. A device according to claim 1, in which the pioot edge bar is made oftwo parts transferring in contrary directions.

JEAN GARRIC.
